And you thought you knew about plastic

Could you give up plastic purchases for one entire week?
[Like not one single thing - including sliced bread bags (just try and buy sandwich bread without 'em) and those teeny things that attach price tags to new clothes. A challenge for this mostly mainstream family, to say the least.]

Want to know more about plastic?

ADDICTED TO PLASTIC
There are more things we don't know about plastics, than things we do...

From styrofoam cups to artificial organs, plastics are perhaps the most ubiquitous and versatile material ever invented. No invention in the past 100 years has had more influence and presence than synthetics. But such progress has had a cost.

For better and for worse, no ecosystem or segment of human activity has escaped the shrink-wrapped grasp of plastic. Addicted To Plastic is a global journey to investigate what we really know about the material of a thousand uses and why there's so darn much of it. On the way we discover a toxic legacy, and the men and women dedicated to cleaning it up.

Check out the upcoming video at: http://www.crypticmoth.com/plastic.php
ADDICTED TO PLASTIC is a feature-length documentary about solutions to plastic pollution. The point-of-view style documentary encompasses three years of filming in 12 countries on 5 continents, including two trips to the middle of the Pacific Ocean where plastic debris accumulates. The film details plastic's path over the last 100 years and provides a wealth of expert interviews on practical and cutting edge solutions to recycling, toxicity and biodegradability. These solutions - which include plastic made from plants - will provide viewers with a hopeful perspective about our future with plastic.

GETTING TO KNOW YOUR PLASTICS
Take a moment to count all of the plastic things in your house.
How many things can you find?
________________
Does our trash have to sit in a landfill? Or can we get more use out of it?

List five things you can do with your plastic waste (other than throwing it away).


Plastic Bag Treasure Hunt!
What does your family do with their shopping bags after they get home from the store?
==============================

What YOU can still do!
Reuse your plastic shopping bags:
  • use them as trash so as not to buy others that are more energy wasting;
  • use them for storage;
  • use paper bags rather than plastic bags when you are given the choice, but keep in mind that paper bags generate 70 percent more air and 50 times more water pollutants than plastic bags, and it takes more than four times as much energy to manufacture a paper bag as it does to manufacture a plastic bag.

PLASTIC CONTAINERS BUYING GUIDE
[from http://www.thegreenguide.com/buying-guide/plastic-containers]


Environmental Impact
Pollution
Considering that plastics are made f
rom non-renewable petroleum and natural gas, it's not surprising to know that plastic manufacturing is a major source of industrial pollution. Producing a 16-oz. #1 PET bottle, for instance, generates more than 100 times the toxic emissions to air and water than making the same size bottle out of glass. Major emissions from plastic production processes include sulfur oxides and nitrous oxides (both of which contribute to global warming) and the chemicals styrene, benzene and trichloroethane.

Plastics Are Forever
When the plastics we throw away escape from garbage trucks or landfills, they get blown into trees and waterways where they're eaten by animals that mistake them for food. In the North Pacific, a floating island of plastic waste the size of Texas has accumulated, doubling in size over the past six years. Some estimates place the load of plastic floating in that area, killing both birds and aquatic life, at 3 million tons.

Nothing in nature, not even sunlight and oxygen, can break apart the bonds that hold plastic together, so it lingers on our planet indefinitely. Rather than biodegrading, plastic photodegrades into dust, winding up in soil and in the air. In bodies of water, the plastic particles absorb other harmful chemicals such as polychlorinated biphenyls (PCBs) and the pesticide DDT. Those particles then get eaten by fish, which wind up back on our dinner plates.

Recycling
Despite the problems with plastic, virtually all types can be recycled a few times before becoming too weak. However, confusing municipal recycling laws and limited access to recyclers who accept all types of plastic have kept recycling rates low; in 2006, a mere 6.9 percent of plastic garbage we generated was recycled.

Personal Health Issues
From production through use and disposal, plastics can expose us to chemicals that are hazardous to our health, including dioxins, phthalates and bisphenol A.

Phthalates: Most cling-wrapped meats, cheeses and other foods sold in delis and grocery stores are wrapped in PVC. To soften #3 PVC plastic into its flexible form, manufacturers add "plasticizers" during production. Traces of these chemicals, known as adipates and phthalates, can leak out of PVC when it comes in contact with foods, especially hot, fatty foods. Adipates and phthalates have been shown to cause birth defects and damage to the liver, kidneys, lungs and reproductive systems in mice. Phthalates are also suspected of interfering with hormones and the reproductive development of baby boys.

Bisphenol A: Many #7 polycarbonate bottles (including baby bottles), microwave ovenware, eating utensils and plastic coatings for metal cans are made with bisphenol A (BPA). Many studies have found that BPA interferes with hormones, as phthalates do, and a March 1998 study in Environmental Health Perspectives (EHP) found that BPA simulates the action of estrogen when tested in human breast cancer cells. A growing number of scientists are concluding, from animal tests, that exposure to BPA raises your risks of heart disease, obesity, diabetes and childhood behavioral problems such as hyperactivity.


Plastic Containers-- What to Look For
Plastics are classified by their "resin identification code"—a number from #1 to #7 that represents a different type of resin. That number is usually imprinted on the bottom of your container; flip it upside down, and you'll see a recycling triangle with the number in the middle.

Here's a quick breakdown of plastic resin types:
#1 polyethylene terephthalate (PET or PETE)Examples: Disposable soft drink and water bottles
#2 high density polyethylene (HDPE)/Examples: Milk jugs, liquid detergent bottles, shampoo bottles
#3 polyvinyl chloride (V or PVC)Examples: Meat wrap, cooking oil bottles, plumbing pipes
#4 low density polyethylene (LDPE)Examples: Cling wrap, grocery bags, sandwich bags
#5 polypropylene (PP)Examples: Cloudy plastic water bottles, yogurt cups/tubs
#6 polystyrene (PS)Examples: Disposable coffee cups, clam-shell take-out containers
#7 other (plastics invented after 1987; includes polycarbonate, or PC, and polylactide, or PLA, plastics made from renewable resources as well as newer plastics labeled "BPA-Free")Examples: Baby bottles, some reusable water bottles, stain-resistant food-storage containers

What To Buy:
#2 HDPE, #4 LDPE and #5 PP: These three types of plastic are your best choices. They transmit no known chemicals into your food and they're generally recyclable; #2 is very commonly accepted by municipal recycling programs, but you may have a more difficult time finding someone to recycle your #4 and #5 containers.

#1 PET: Fine for single use and widely accepted by municipal recyclers; avoid reusing #1 water and soda bottles, as they're hard to clean, and because plastic is porous, these bottles absorb flavors and bacteria that you can't get rid of.

PLA: plastics made from renewable resources such as corn, potatoes and sugar cane and anything else with a high starch content; although you can't recycle these plant-based plastics, you can compost them in a municipal composter or in your backyard compost heap.

Plastics to Avoid:
#3 PVC: Used frequently in cling wraps for meat, PVC contains softeners called
phthalates that interfere with hormonal development, and its manufacture and incineration release dioxin, a potent carcinogen and hormone disruptor.
#6 PS: Polystyrene-foam cups and clear plastic take-out containers can leach styrene, a possible human carcinogen, into food.
#7 PC: The only plastic made with
bisphenol A, polycarbonate is used in baby bottles, 5-gallon water-cooler bottles and the epoxy linings of tin food cans. Bisphenol A has been linked to a wide variety of problems such as heart disease and obesity.

Shopping Tips
Plastics are classified by their "resin identification code"—a number from #1 to #7 that represents a different type of resin. That number is usually imprinted on the bottom of your container; flip it upside down, and you'll see a recycling triangle with the number in the middle.

When purchasing cling-wrapped food from the supermarket or deli, slice off a thin layer where the food came into contact with the plastic and store the rest in a glass or ceramic container or wrap it in non-PVC cling wrap.

Usage Tips
Avoid storing fatty foods, such as meat and cheese, in plastic containers or plastic wrap.

Hand-wash reusable containers gently with a nonabrasive soap; dishwashers and harsh detergents can scratch plastic, making hospitable homes for bacteria.

A "microwave-safe" or "microwavable" label on a plastic container only means that it shouldn't melt, crack or fall apart when used in the microwave. The label is no guarantee that containers don't leach chemicals into into foods when heated. Use glass or ceramic containers instead.
